The process of seeking planning permission for development in London can seem intricate, involving multiple stages, stakeholders, and regulatory frameworks. Whether you are a resident looking to extend your home, a developer proposing a new building, or an urbanism enthusiast interested in the city’s growth, understanding this process is crucial. This wiki page aims to demystify the London planning application journey, from initial submission to the final decision.

Key Stages of a Planning Application

The planning application process in London, overseen by individual London boroughs and the Greater London Authority (GLA) for larger or strategic sites, generally follows these key phases:

Pre-application Advice

Before formally submitting an application, it is highly recommended to seek pre-application advice from the relevant local planning authority. This stage allows you to discuss your proposal, understand potential issues, and ascertain whether your development is likely to comply with local and national planning policies. This can save time and resources in the long run.

Submission of the Application

The application is formally submitted to the local planning authority. This typically involves completing specific forms, providing detailed plans, drawings, and supporting documents (such as design and access statements, heritage statements, or environmental impact assessments, depending on the scale and nature of the development).

Validation

The local planning authority will check if the submitted application is complete and meets all necessary requirements. If it is valid, it will be registered and assigned a planning officer. If it is invalid, you will be notified of the missing information.

Consultation and Publicity

Once validated, the application is publicised. This usually involves notifying neighbours, displaying site notices, and advertising in local newspapers or online. Interested parties, including residents, community groups, and statutory consultees (like Historic England or the Environment Agency), are invited to submit comments within a specified timeframe.

Assessment

The planning officer will assess the application against relevant local and national planning policies, including the London Plan, the borough’s Local Plan, and any supplementary planning documents. They will consider the comments received during the consultation period, site visits, and any other material considerations.

Decision

The decision is usually made by either the Head of Planning (under delegated powers) for minor applications or by the borough’s Planning Committee for more significant or contentious proposals. The decision will be either to grant planning permission (often with conditions) or to refuse it. Applicants have the right to appeal a refusal.

Post-Decision

If permission is granted, there may be conditions attached that need to be discharged before or during development. Appeals can be lodged if permission is refused or if the applicant is unhappy with the conditions.

Material Considerations

When determining a planning application, planning officers and committees consider “material considerations.” These can include:

National and local planning policies
Previous planning decisions
The design and appearance of the proposed development
Impact on neighbouring amenity (e.g., loss of light, overlooking, noise)
Traffic and highway safety
Environmental impacts (e.g., flood risk, biodiversity)
Economic benefits
Community infrastructure needs

What is NOT a Material Consideration?

Some factors are not considered material and cannot influence a planning decision, such as:

Loss of a private view
Moral objections to the applicant
Decline in property values
Private rights of way or property boundaries (these are civil matters)
